IPC: H01L29/80
Filed: 1990-02-06
Abstract: PURPOSE:To obtain a circuit simulator having a model expression which does not require any fitting by introducing parameters which represent the VDS dependency of a parameter representing the K factor. CONSTITUTION:In connection with the DC volt-ampere characteristic of a GaAs MESFET, such model expressions as Equations I-IV are used as expressions representing the electric current ID flowing between a drain and source. The Vth, Vt0, and eta of the equations respectively represent the threshold voltage, the threshold voltage when VDS=0, and the parameter representing the drain- source voltage dependency of the threshold voltage. The VDS, VGS, and (b) of the equations respectively represent the drain voltage to the source, gate voltage to the source, and correction factor for the electric current flowing between the drain and source. In addition, the Vh, beta0, and lambda and alpha respectively represent the correction offset voltage to the electric current flowing between the drain and source when the gate voltage to the source is high, a parameter representing the K factor, and parameters representing the VDS dependency of the beta. Therefore, all of the parameters of the equations can be found by measurement without making any fitting.

Filed: 1980-02-29
Abstract: PURPOSE:To transmit data through the master station between arbitrary stations, by receiving the transmission request signal from a slave station to transmit the designation signal for transmission station to this slave station and by designating the master station itself as the receiving station. CONSTITUTION:Slave station 2 transmits the transmission request signal to master station 1. The master station transmits the designation signal for transmission station to this slave station and designates the master station itself as the receiving station. When master station 1 transmits the transmission start signal to slave station 2, slave station 2 transmits the designation desired number for receiving station  through master station 1 to slave stations 2' and 2''. Master station 1 transmits this designation desired number to slave stations 2' and 2'' and transmits the transmission start signal to slave station 2. Thus, slave station 2 puts transmission data onto line 3, and slave stations 2' and 2'' receive this data, and thus, data is transmitted through master station 1 between arbitrary slave stations.

Filed: 1981-02-24
Abstract: PURPOSE:To prevent an unused film from going into a patrone for a camera in which the film is rewound every a frame after the film is preliminarily wound, by securing a coupled operation between the opening/closing of the camera back cover and the switch of a motor driving circuit. CONSTITUTION:A driving circuit of a motor M includes a switch 43 which closes with the opening/closing of the camera back cover, switches 40' and 40'' which are changed over with the loading of a film patrone, a power supply switch 44 coupling to a release, and switches 45 and 45' coupling to the film transportation. When the film is loaded, the switches 40' and 40'' are switched to the side of a terminal (a) along with the switch 43 opened. Therefore the film is never  put into the patrone although the release is operated. The motor winds up the  film completely with the closure of the switch 43. When the switches 40' and  40'' are turned manually to the side of a terminal (b) and released, the film is rewound by a frame.

FF6 stores the output of the comparator. In this case, the pulse width of the output Tt is set to a integral multiple of the period t in which the measured current changes, enabling the discrimination of the propriety with excellent reproducibility independently of the start time of integration.
